After the intrusion of nature gas or air into drilling liquid
during drilling, the density becomes lower, the viscosity will be
higher and the annulus drilling liquid density will be lower, which
will cause hydrostatic column pressure decrease. Thus, these
accidents such as blow out and borehole collapse will happen.
ZCQ vacuum degasser can solve gas troubles of the drilling fluid
effectively. The bubbles in mud are transported to the drilling
liquid surface quickly and separated from liquid after the
treatment. Meanwhile, the self lock of hydraulic cones on
centrifugal pump caused by aircut can be avoided.
A suitable vacuum area will form in the top part of degassing
compartment during degasser working and the mud will flow into the
degassing tank fluently.
Special separation pan design makes a thin liquid layer form and
the air in the mud can be removed quickly.
Mud fast sprays onto the wall through the rotator windows and mud
bubbles can break completely with a satisfactory degassing.
Gas-water separator will not make water and gas be discharged
simultaneously which assures a smooth gas outlet pipe. Meanwhile,
it can also circularly provide water for vacuum pump, saving water.
Suction pipe can act as a heavy-power agitator when there is no
aircut in mud.
